BMW F80/F82/F87, M3/M4/M2 Titanium Valved Equal Length Z Pipe Catback Exhaust

The ultimate exhaust for the S55-powered BMW F80 M3, F82 M4 and F87 M2 Competition. A full titanium valved system from the downpipes back, with an equal-length Z pipe mid section, a valved rear muffler, quad tips and the wireless valve remote kit supplied.

The S55's two turbochargers feed the exhaust unevenly on a factory system, which is where much of its flat, raspy note comes from. The equal-length Z pipe gives both banks matched-length pipes and crosses them over before the muffler, balancing the pulses for a smoother, fuller tone underneath the sharp titanium top end - while cutting a substantial amount of weight from the car.

Crafted from aerospace-grade titanium with precision TIG welding, hand heat-anodised in your choice of Blue, Purple or Gold, and supplied complete with the valve remote kit and all hardware.

Key Features

Full Titanium Construction

Manufactured from high-grade titanium for exceptional strength, corrosion resistance and substantial weight savings over both the factory and stainless steel systems.

Equal-Length Z Pipe Mid Section

Both turbochargers feed matched-length pipes that twist across each other before the muffler, balancing pulses for a smoother, fuller exhaust note and consistent flow.

Integrated Valved Exhaust System

Electronically controlled valves switch between a refined OEM+ sound and a fully open, race-inspired exhaust tone, controlled from the supplied wireless remote.

Full System From The Downpipes Back

Replaces the entire factory exhaust behind the downpipes in one kit - mid section, rear muffler and tips.

Quad Tips In Your Choice Of Finish

Black, chrome or carbon fibre style tips, selected at checkout.

Signature Titanium Exhaust Note

A sharper, higher-pitched and more exotic tone unique to titanium, with enhanced crackles, pops and high-RPM sound.

Direct Bolt-On Fitment

Designed specifically for the F80, F82 and F87 using factory mounting locations for straightforward installation.

Choose Your Titanium Finish

The colour on a titanium exhaust is produced by heat, not by paint or coating, and it runs through the pipework and muffler body as one continuous finish. Three options are available:

Blue - the finish shown in our photography. Deep blue through the piping, with the twisted Z pipe section left in natural titanium and gold and violet heat banding across the muffler body.

Purple - rich purple and magenta across the system with bronze shading over the muffler body.

Gold - warm bronze and gold dominant, with blue and violet coming through at the bends and weld lines.

Because the finish is created by heat, no two systems are identical and the banding will vary slightly from the photographs. That variation is characteristic of anodised titanium rather than a fault. Tip finish is selected separately above.

Performance Benefits

When paired with supporting modifications and tuning, this exhaust system can provide:

• Significant weight reduction over the factory exhaust
• Faster turbo spool and improved throttle response
• Increased exhaust flow and reduced backpressure
• A smoother, fuller and more aggressive S55 exhaust tone
• Enhanced high-RPM sound and driving engagement

Performance gains may vary depending on supporting modifications and tuning.

3.0L Twin-Turbocharged S55 Engine

The M2 has a shorter wheelbase than the M3 and M4, so each system is built to the length of its car - select your model at checkout. The 2016-2018 M2 (N55 engine) is not covered by this system.
